Addition of nano-silica effected to increase the content of calcium hydrasilicate and to decrease the content of calcium oxide for resulting the hydrate cement. Additional mass percent of nanosilica in all three cements of 1.0 % was important to increase compressive strength because the formation of calcium hydrasilicate is increased and the content of calcium oxide is decreased which were become from the results of X-ray diffraction analysis. Therefore, the addition of nanosilica of 1.0 % is optimal dosage. This is related to the dissolution of calcium hydroxideБаатарцэрэн Д, Жавхлантөгс Н, Цэрэнханд Б

<p>This study shows hill slope process of Mt. Ovoot in the northeast of Khangai Mountain Range, Mongolia. This work is mainly focused on sediment transportation by surface and subsurface flows in Mt. Ovoot based on movement of microelements within soil profiles along the mountain slopes and measurement of particle sizes and shapes of the soils. The main purpose is (1) to determine the chemical and physical properties of soils, and (2) to reveal hill slope process with movements of microelements. Movement of the microelements show intensive slope processes in the Mt. Ovoot. <br />Each surface soil on upper slope contains microelements less than those on lower slope of the mountain, where sediments have been more round and finer. It infers that more soils are eroded and accumulated on upper and lower slopes, respectively, these transport and deposition of the soil particles are caused by the surface and subsurface flows.</p>Даваахүү Ц, Орхонсэлэнгэ А

Geothermal exploration involves geology, geochemistry and geophysics. In geophysical exploration, resistivity surveying plays a most important role in delineating the reservoir. The parameters that control the geothermal system show a strong response to electrical resistivity. The resistivity methods that are mostly used in geothermal exploration in Iceland are TEM (Transient electromagnetics) and MT (Magnetotellurics). The resulting resistivity cross sections and resistivity depth slices, show a shallow lying low resistivity layer and deep lying low resistivity towards the end of the cross sectionsСаранцэцэг Л, Hersir P G, Arnason К

<p>Various natural products derived from plants and animals have being played important role in the treatment of human diseases for many centuries. One of those products is poll gland secretion of camel (Camelus bactrianus). During rutting season poll gland of male camel becomes bigger and produces secretion. In traditional medicine, poll gland secretion is used in cancer treatment especially breast cancer, anti-inflammation, softening gall-stone and some other treatments. In this study, we isolated total protein from poll gland of camel, and detected antioxidant activity and studied effects of secretion protein in vitro cancer and non-cancer cell lines. <br />Antioxidant activity was correlated with their protein level. The half maximal inhibitory concentration of cancer cell (IC50) was identified differently in cell lines, IC50 of HCC1397 breast cancer cell line was at 407µg/ml concentration of protein whereas IC50 of HepG2 liver cancer cell line was at 215µg/ml. The protein had effect in cancer cell mobility by suppressing 80% to 100% when the protein concentration was 200µg/ml. Our result showed that the poll gland protein has negative effects to some genes such as CASP3 and CASP8 which are involved in cell apoptosis.</p>Номин М, Бадамгарав Ц, Цэрэндулам Б, Батжаргал Б

<p>We isolated lactic acid bacteria from fermented dairy products, fermented mare’s milk and cow yogurt, which are traditionally produced by Mongolian herders, and carried out in vitro study of their probiotic properties. Culture 44c is 100% identical to species Lactobacillus helveticus (Lhelveticus) or a strain KT368987, isolated from Mongolian airag, while culture 65b is 99% identical to Lactobacillus delbreuckii subsp. bulgaricus (L.bulgaricus) or strain CP016393 isolated from camel fermented milk in Gobi-Altai aimag and characteristics of both cultures were the best among all cultures obtained in the present study. Isolated lactic acid rods completely inhibited the growth of gastro-intestinal pathogens which spread among livestock (E.coli 09, E.coli 026, S.abortusovis 0068) and Mongolian population (S.aureus 5695, S.aureus 5068, S.aureus SA27, E.coli 10963, E.coli 10977). As well as, we determined the properties, including resistance to the acidic environment of digestive tract and activity when using with common antibiotics, which are the basic requirements for bacterial strains used in functional food production. <br />According to the result, when pH of the environment reached 3.5 or 4.0, growth rate of the strains was over 80 percent and the lactic acid strains were variably resistant to 10 antibiotics of 5 classes (penicillin, aminoglycoside, cephalosporin and macrolide). For example; Formation of 8.9±0.87 mm zone around all antibiotic discs for culture 44c of L.helveticus demonstrates the culture can be used in combination with these antibiotics for therapeutic purposes. Besides of these characteristics, CFU per ml was determined by growing on MRS nutrient medium under anaerobic condition. Moreover, CFU/ml was determined because its spectrum of activity depends on the number of bacteria per 1ml. L.helveticus 44c reached its highest volume (2503х1010) at 48th hour of growth, while L.bulgaricus 65b reached its highest volume (2503х1010) at 72th hour of growth. After they reached their highest volume, both of them tended to decrease. For this reason, these strains, especially L.helveticus 44c and L.bulgaricus 65b strains, are possible to be used as a source material for probiotics or functional food products.</p>Хандсүрэн Б, Дэмбэрэл Ш, Дүгэрсүрэн Ж

<p>The skin is thin layer of tissue forming the natural outer covering of the body of a person, it is protected from some infections [1]. Skin’s naturally occurring microbes are Staphylococcus, Micrococcus, Corynebacterium, Brevibacteria, Propionibacteria and Acinetobacteria [2, 3]. <br />Acnes caused by Propionibacterium acnes (P.acnes) infection but it is commensal with other microorganisms. Sometimes P.acnes identified in normal skin. P. acnes live deep within follicles oil-bag and pores, away from the surface of the skin. Elevated production of sebum by hyperactive sebaceous glands (sebaceous hyperplasia) or blockage of the follicle can cause P. acnes to grow and multiply. Acne is chronic inflammatory disease affecting the pilosebaceous follicle [18]. Skin infections are decreasing immunity of certain parts of the body.<br />Acne severity correlated highly with increasing stress and harmful for self-confidence [4]. <br />The most countries had study about their acne patient’s microflora and pathogenic microbes. Currently, our country has not been study yet. Therefore, we carried out research to determine the relationship between Mongolian samples of acne and acne causing their pathogenic microorganisms.<br />We were interested microflora of Mongolian acne patients. We took samples by swab and obtained from 40 acne patients. The acne patients were 25 females and 15 males with teenagers of 57.5% and 25-52 years old of 42.5%. The samples were cultured on modified GAM agar (Nissui, Japan) under anaerobic conditions at 37°C for 96 hr. P. acnes was identified by PCR and the 16s rRNA gene sequences. Also the samples were cultured on Nutrient agar (Biolab, Hungary), Tryptose soy agar (Biolab, Hungary) in aerobic conditions at 37°C for 48 hr. Staphylococcus epidermidis, Staphylococcus aureus, Micrococcus spp, Staphylococcus capitis and Staphylococcus cohnii were identified by API-STAPH-IDENT (Biomerieux, France). We detected demodex mite by microscope.<br />We were found demodex 45% of all patient. All patients had S.epidermidis, P.acnes had 30% of them, S.aureus in 47.5%, Micrococcus, spp in 27.5%, S.Capitis and S.Cohnii each 5%. We compared our research result with Germany, French, Indian and Japanese researcher’s similar studies. Whereas our research results were more than European acne patients such as P.acnes 16 percent and Staphylococcus 64 percent. However Mongolian acne patient’s microorganisms determined more than European acne patients, P.acnes determined 32 percent lower than Japan and Indian patients. Even though Staphylococcus was 47 percent more than their result.<br />Our study shows in causing acne, especially severe acne is associated cases demodex mite, P. Acnes, S.epidermidis. And the strains of bacteria S.aureus, Micrococcus spp conditions from acne were related degree occur in acne but complications. Appearance acne bacteria S. capitis, S.cohnii samples, but only casually. Mongolian people causing acne, pathogenic species had a relatively high percent of people in other countries, S.epidermidis acne compared to the complete condition pathogenic type of acne vulgaris.</p>Оюунбилэг Н, Энхцацрал М, Болортуяа Б, Даваапүрэв Б, Чинзориг Р, Анзай Ё, Номиндалай Г, Энхжаргал Ж, Батхүү Ж

<p>Horses are loved by Mongolians in their culture and nomadic lifestyle. Mongolian horses made a great contribution to Mongolian history.<br />The art work of ‘The Eight Steed of Genghis’ is well known by us. While Chinese artist Xu Beihong (1895-1953) great work ‘Eight Chun map’ has its root in West Zhou Dynasty’s (B.C. 1046-B.C. 661) art work which was drawn by fifth king Zhou Muwang (B.C. 1054-B.C. 949). Similarly there maybe a connection between the ‘Lucky Eight Horses’ in art works even sculptures with the Mongolian art called ‘The Eight Steed of Genghis’.<br />This article aims to explain the meaning of the word ‘Sharga agt tan’ as used in “The Secret History of Mongolia” which was written in the 13th century, is considered to have no outside influences and believed to be an accurate account of Mongolian history. It especially aims to explain the meaning of the suffix tan that is used in the phrase ‘Sharga agt tan’ in “The Secret History of Mongolia”. The suffix tan was used in the middle aged Mongolian language and in our study you can see the comparison of the suffix tan and its similar meaning in contemporary Mongolian language. This article also aims to determine the actual number of horses in the phrase such as ‘Sharga agt tan 9 morid’ (meaning of nine yellowish/ light bay horses), ‘Sharga agt tan 8 morid’ (meaning of eight yellowish/ light bay horses), as well it attempts to explain that in the mongolian language the word sharga means yellowish/light bay colour in cognitive linguistic understanding. This study also explores the meaning of the expression ‘The Eight Sharga Steed of Genghis’.</p>Сүмбэр Б
